• 32位ADC芯片的前端设置问题

    在寻求一款32位ADC芯片,需要的采样频率在4kHz~16kHz,ADC输出频率1kHZ,有效分辨率至少20位。

    希望ADC前端的低通滤波把系统带宽限制在840Hz。查询到LTC2508-32,LTC2500-32以及AD7177-2三款产品,

    想了解如下情况:

           1、不知道还有没有可推荐的32位ADC?

           2、我的信号是单端输入,应该需要一个单端转差分的运放,希望该放大器有可配置低通滤波器,这样可以简单地设置

    低通滤波截止频率在840Hz,能否推荐一些满足要求的放大器?

  • LTC2500-32

    Hi

    I am testing averaging filter in LTC2500-32.

    The test conditions are as follows.
    - Preset Mode(PRE PIN '1', SDI '1') : Averaging filter, with DGC and DGE off
    - MCLK : 2000sps
    - DF : 20

    I read the ADC value through SPI every 20 MCLKs using…

    When PER and SDIA pin are high level DRL has normal pulse output.

    DRL signal cannot be output in other modes.

    SDOA output is always low when reading data.

    Is it caused by the wrong timing in the diagram?

                 Thanks!

  • LTC2500-32

    Hi there,

          I would like to use LT2500 in my project. The input signal is about 0.1Hz~10Hz, +/-10V, single end. The low noice and low drift come first. And I notice that LTC6363+LTC2500 in the typical application of datasheet. I just donot know how to…

  • LTC2500-32 ENOB

    Hi ADI Expert, 

    According to the datasheet page8 of LTC2500-32 Performance characteristics,

    SNR: 116dB, SINAD:114dB @ 128K FFT, SSINC filter. thus I calculated the ENOB= SINAD 114dB -1.76dB/6.02 = 18.6 Bits.

    The datasheet page32 table2 is noise performance…

  • RE: Which parts/strategy do you recommend for isolation of ADI's 32 bits SAR ADC?

    On behalf of Eric Benedict:

    Which ADC are you interested in and what are your application requirements? 

     

    The LTM2893 could be a good solution for the LTC2508-32 which is configured with pin strapping. 

     

    The LTC2500-32 has features which require SPI…

  • AD5930/32 Suitability

    Hi,

    I have a requirement to produce a sinewave which is nominally 1MHz but that can be digitally changed in 1kHz steps up to +/-50kHz. It has to be stable to +/-100Hz between 50 & 125 degC. The digital update rate is << 1Hz.

    Would the AD5930…

  • LTC2500-32 exposed pad

    Hello,

    I would like to ask if there is any problem with leaving the exposed pad(Pin 25) of LTC2500-32 floating.

    Thanks!

  • ADIS 16460 32 bit

    Hello, 
    I'm trying to read 32 bits at 2048 Hz, out of all 6 sensors. I found that I can only read 9 times 16 bit, that means if I read 32 bit I only read 4.5 sensors and not all 6. When I try to read beyond the 9 times the 16 bit, I get on DR pin, errors…
